Windows 7 has native support for [url="http://en.wikipedia.org/wiki/AVCHD"]AVCHD[/url] which is nothing but H.264/AC3 inside a m2ts container. This means that Windows Media Center can now play these files natively.
Most MKV media that I have seen (personally I have just two MKV files) is H.264 with AC3 audio. So all I needed to do was change the container from mkv to m2ts. Since this method does not need any lossy transcoding, it is far easier and much faster. As long as your source is good, the result is pretty much guaranteed.

Procedure:
1. Start tsMuxer and add your MKV clip in the input section

2. In the Tracks section check if you see expected tracks. I included the subtitle track but apparently WMC and WMP don't use it.
3. Did not do anything in the General track options setting
4. In the Output section select M2TS muxing and select desired location.
5. Now hit Start muxing button at the bottom.
[attachment=224156:snip2.PNG]
6. Depending on your PC, it will take 5-10mins to perform a pass through conversion of the clip.
7. If all goes well, Windows Explorer will display a thumbnail for this. Try playing it in WMP and check if it plays without problems.
8. Now move the m2ts file to your Video library.
OR
8. Media Center has a special library called "Movie Library" that you can setup from its settings. e.g. e:\Movies. Move the m2ts file to this location.
9. Now give Windows Search enough time to index the new file. For me it was roughly 5mins.
10. Launch WMC from Xbox 360
11. Navigate to either [i]Pictures + Videos>video library[/i] or [i]Movies>movie library[/i] and play the file.

For me this worked without any problems at the very first attempt. I haven't experimented much with tsMuxer besides whatever I wrote above. This obviously will not work through the dashboard since Xbox 360 doesn't recognize the format (it did not show up in list for me). I am sure they will add the support soon because all consumer HD camcorders use m2ts(or mts) files. PS3 probably supports m2ts format already because of Sony's handycam connection.

Hope this helps people who have Windows 7 installed. I am using build 7057. Although Media Center can be shaky at times so YMMV.

[quote name='Revolution.' post='590804010' date='Apr 3 2009, 21:01']yeah but whats the point, you might as well convert it to a format it understands..

cbb until they release native support for most formats..

but nice work doing all this work [/quote]
I don't know when MS will support MKV - probably never, knowing how long it took them to do H.264. Besides this is much better than lossy conversion. IMO anyway.

IIRC it is not possible to stream AC3 5.1 or DTS to the 360 if you remux H264 content.

That's from the creators of MKV2VOB and PS3Media Server.

If you want AC3 5.1 I believe you have to transcode. DTS is just not possible full stop - It only works on the PS3 as the creators of the above applications found a way to trick the PS3 into sending the DTS sound track to your receiver untouched, so your receiver is actually decoding it, not the PS3. It's done by confusing the PS3 into thinking the track is 2 channel PCM, but when it actually reaches your receiver, your receiver knows its DTS and not 2.0 PCM.

If the 360 supported LPCM I believe they may have been able to do the same trick, but the 360 doesn't support HD audio.

People need to understand MKV support on either the 360 or PS3 wouldn't really change anything, it's just a container, codec support is what matters most. Containers can easily be changed.

From 3r1c (MKV2VOB)

[quote]There is no way to get x264+ac3 working on xbox 360.

There is 3 ways:
1. convert the ac3 to aac stereo and mux to mp4
2. convert the video to mpeg2+ac3.
3. convert the video+audio to WMV[/quote]

[quote]With transcoding set to always and codec set to xvid, mkv2vob will create xbox360 playable files.
but it converts the video not the audio, this will take much longer then AAC conversion.
But with AAC you will only get stereo, with xvid you get to keep the ac3 5.1[/quote]

So it's either/or - You can get 5.1 if you transcode video, but if you remux video you get stereo AAC.

Media Center is independent of the Xbox dashboard. That's why with Vista you couldn't play Xvid in WMC but you could do it in the dashboard. Windows 7 Media Center now supports AVCHD which is H.264 + AC3. I think I was able to play 5.1. I will check that later today.

Your own screenshots show it downmixing to two channel AC3. (I think, I've never used either of those programs)

edit: Nevermind, it looks like its just demuxing and muxing it, not downmixing.

Mate, u're doing it wrong and don't understand a lot of stuff, let me show u it ...

As AB already wrote a lot of interesting stuff, I'm gonna add some stuff to this thread since I own both consoles and know my way around playing mkv on both.

1- The xbox CANNOT play 5.1 AC3 out of the box.
2- The xbox CAN play H264 content up to profile 4.1
3- The xbox CANNOT play files with a DTS track AT ALL ! ( except DVDs and HDDVDs if you still have one )
4- The xbox CAN play H264 files with an AC3 track once the profile is changed ( see n

I never tried to play a m2ts file with Media Center since the Xbox can already play them via the dashboard

what a waste of time, i just installed the codecs ran xbox 360 media center ext, and played the file! Windows 7 build 7000-7077 has allways done this for me!

I don't quite understand how software on your PC can magically change the codec support built into the 360 firmware?

Are you sure Vista Media Center isn't transcoding?

Umm, no you did not. MKVs won't be shown in the media center no matter what you do. Although I will be glad if proven wrong. Will save me time. Can you elaborate?

I have no idea how [url="http://en.wikipedia.org/wiki/Windows_Media_Center_Extender"]media center extenders[/url] render video. I am guessing that it doesn't involve the dashboard at all (beyond launching the extender app). For a while other extenders were supporting xvidd, divx and h264 whereas xbox 360 extender (vista) did not. But now with Windows 7, they all work on 360.
Audio, did you ever try running AVCHD(.mts, .m2ts) content on PS3? wikipedia says PS3 supports it natively.

Yeah I'm just wondering because native video playback either off hard drive or streaming depends on the codecs your console supports, not your PC. The only time PC codecs matter is if you require to transcode a video on your PC first before streaming it.
